Details:

The values of the variables "num_col" and "ncc" change unexpectedly from 1000
to values such as 10, 48, or 49. Likewise, the values of the variables
"num_row" and "nrr" change unexpectedly from 2 to 50, 10, or otherwise.

I did not update the values of these variables. 

Furthermore, the following print statements are repeated unexpectedly.

printf('###             Number of rows: %dn',num_row)
printf('###             Number of columns: %dn',num_col)
printf('===             Number of rows: %dn',int2str(nrr))
printf('===             Number of columns: %dn',int2str(ncc))


The behavior of the script is nondeterministic, but is repeatable.

I executed the script with an input argument (filename of the log file).
process_sin_tb.m sin_tb.dat



The following is an extract from the terminal session of executing the GNU
Octave script.

status =  0.00000000000000e+00
num_row = 10000

nrr = 10000

status =  0.00000000000000e+00
num_col = 2

ncc = 2
